A student solving for the acceleration of an object has applied appropriate physics principles and obtained the expression a = a₁ + Fm where a₁ = 3.00 meter/second², F = 12.0 kilogram⋅meter/second² and m =7.00 kilogram. First, which of the following is the correct step for obtaining a common denominator for the two fractions in the expression in solving for a?

a. (m/m times a₁/1) + (1/1 times F/m)

b. (1/m times a₁/1) + (1/m times F/m)

c. (m/m times a₁/1) + (F/F times F/m)

d. (m/m times a₁/1) +(m/m times F/m )

## Answers ( )

Answer:The correct option is option (a).The acceleration of an object ism/s².Explanation:Given expression is

[ divide a whole number by 1 to turn into a fraction. Since is a whole number, so is divided by 1 to turn into a fraction]

[The l.c.m of the denominators 1 and m is m. Now multiply both numerator and denominator by m of and multiply both numerator and denominator by 1 of ]

The correct option is option (a)Given that,F= 12.0 kg.m/s² , m=7.00 kg and = 3.00 m/s²

m/s²

The acceleration of an object ism/s².
